Dredge Pump
The main features of Dredge Pump are:
1. The overall structure Marine sex is good
A. Structure is simple,reliable
B. Easy to tear open outfit,easy maintenance
2. Dredging good performance
A. Cavitation performance is good
B. The flow ability,wide applicability
C. Performance curve steep drop
D. Can realize a variety of pump performance deployment
3. Wear-resisting performance is good,over-current components long life
4. Hydraulic loss is small,high efficiency,low power consumption
5. Shaft seal and reliable,and no leakage
6. Electric barring institutions,saves time and effort
Theory: Centrifugal pump
Usage: Slurry mud
Fuel: Diesel
Pressure: High pressure
Power: Hydraulic
Standard: Nonstandard
The main Features of Single-walled Dredge Pump are
- Long working life in abrasive conditions
- Efficiency up to 92% (as measured in practice) resulting in lower fuel consumption at unchanged production
- Reduced and more even wear, resulting in longer lifetime of wear parts
- Better performance as a result of the low net positive
- Suction head required (NPSHR)
- Highly versatile application due to steep flow head ratio curve
- Limited influence of wear on pump performance
- Wear-susceptible parts are available in abrasion-resistant materials
- Easy to disassemble for inspection and repair
